Canelo Alvarez and Amir Khan are set to meet face-to-face one day before their middleweight title fight. The two boxers will weigh in on Friday at T-Mobile Arena for their bout, which will be fought at a catchweight of 155 pounds.

Much has been made about the catchweight in this fight, considering Khan has never fought at more than 147 pounds before. He made the jump to welterweight just two years ago, having previously been a light welterweight champion. Fighting for the middleweight title, Khan is technically making a two-division jump, surpassing light middleweight.

Alvarez holds the WBC middleweight title, even though he’s never fought at 160 pounds. Saturday will mark his fifth straight fight at 155 pounds. He’s won his previous four fights, most recently defeating Miguel Cotto by unanimous decision. Alvarez was last beaten by Floyd Mayweather in September 2013, suffering the only loss of his career when he fought at 152 pounds.

Khan enters Saturday’s bout on a five fight winning streak. It will be the first time he’s fighting in the main event of a pay-per-view in the United States.
